INTRODUCTION
The RIMIG205I is a Multi-Process welder that incorporates MIG and MMA welding in one unit.
Adopting the most advanced inverter technology, the RIMIG205I uses Power Inverters and PWM
technology, which works by rectifying the mains AC input voltage. The rectied input voltage is then
inverted and ltered to a smooth DC current. The smoothed DC current is then sent through power
switches (Mosphets) which convert it back to a high frequency AC voltage. The AC voltage is then stepped
down by a transformer and rectied to DC. The rectied DC is then ltered and smooth for a usable power
output for welding.
The development of inverter welding machines has massive benets which include greatly reduced size
and weight, greater power efciency, multi-process capabilities and many more. The Inverter welder’s
power source produces a much stronger and concentrated stable arc which results in better quality and
more efcient welds.
In MMA mode, this unit is a constant currant DC MMA (Arc) inverter welder. In MIG mode, this unit is a
constant voltage DC MIG (Gas and Gasless) inverter welder. The MIG series is a very efcient and robust
machine. Using advanced technology coupled with an array of adjustment controls they produce superior
MIG welds. The advanced feature of polarity adjustment allows the welders to use Gas or Gasless MIG
wire.
The small size and weight of the machine coupled with it being generator friendly makes it a perfect
candidate for those on-site jobs requiring portability.

Wire Speed:
In MIG mode it adjusts the wire speed and proportionately affects the amperage. The increase in
wire speed determines the amount of weld penetration. Too high of a wire speed will result in a burn
through. It is important to correlate the welding voltage and the wire speed to achieve the desired
result. It is highly recommended that you practice on a scrap piece of metal to determine what wire
speed and voltage combination is suitable for the metal to be welded. The chart below is a good
starting point of voltage and wire speed settings that can be used in relation to the welding wire
diameter.
MIG Voltage & MMA Amperage:
In MMA mode you can adjust the output amperage. In MIG mode it adjusts the welding voltage
which determines the width and height of the bead. Turning the knob clockwise increases the
welding voltage. There is a correlation between the welding voltage and the arc length. A short
arc length will decrease the voltage which will result in a narrow, "ropey" bead. A longer arc length
(obtained by increasing the voltage) will produce a more at and wider bead. An excessive arc length
will yield an incredibly at bead or an undercutting of the weld metal. It is highly recommended that
you practice on a scrap piece of metal to determine what voltage is suitable for the metal to be
welded.

INSTALLATION & OPERATION OF MIG
1. Turn the mode selector switch to MIG and the function switch to MIG TORCH.
2. If using gas assisted (solid) wire, turn the mode selector to "standard". Connect the gas bottle with the ow
meter and a gas hose to the back of the machine, secure the gas bottle so it cannot fall over.
3. MIG welding with:
A) SOLID WIRE: Insert the earth cable quick connector (jack plug) into the negative dinse socket output
in the front panel and the clamp on to the work piece. Insert the MIG quick connector (jack plug) into the
positive dinse socket output in the front panel.
B) GASLESS WIRE: Change the polarity on the selector front panel located on front panel. Always ensure
that the polarity is changed back for welding with Gas.
4. Fit the MIG wire on to the spool adaptor and ensure wire direction is a clockwise rotation to feed the wire
out.
5. Choose drive roll and contact tip appropriate to your wire size.
6. Loosen the pressure wheel, t wire through the spring inlet guide over drive roll and through the outlet
guide, close the pressure wheel and adjust pressure so wire feeds through but can slip if wire gets jammed.
7. Fit the wire into the torch by hand and then tighten the torch on to the euro output socket.
8. Press the trigger button to feed wire to end of torch tip. Weld with a distance/stick out of about 10 times the
wire thickness.
• Open the valve of the gas cylinder and adjust the ow rate to 10 to 15 LPM (Litres per Minute).
• Adjust the voltage, choke and wire speed (amperage) knob to the correct settings based on the thickness of
the work piece and wire diameter.
• Press the torch switch to feed out the wire and gas and begin to work.
The machine is equipped with a power voltage regulator. When power voltage moves between ± 10 % of
rated voltage, it will still work normally.
Should an extension cable be required (not recommended), a cord gauge of not less than 2.5mm is
suggested and not longer than 10 meters.
To prevent the cooling system malfunctioning, make sure the fan intake of the machine is not covered or
blocked

1. Turn the mode selector switch to MMA
2. The electrode holder and earth clamp are easily connected to the machine by inserting the quick connector
and twisting it clockwise. Always ensure a tight t.
3. Generally, Reverse Polarity is used in which the welder’s electrode holder will be connected in the “+”
Positive Terminal while the earth clamp is in the “- “Negative Terminal. The welder does have the ability to
be used for Straight Polarity or Reverse Polarity. We recommend you connect the polarity in accordance
with the Electrode Manufacturers recommendations. If the polarity is connected incorrectly it will cause an
unstable arc, spatter, and/or the electrode to stick. If these symptoms occur change the polarity.
4. Set the amperage knob according to type and size of welding rod being used and the arc force to the
desired penetration required.
